DISPLAY APPARATUS; f

t To zZZfwwm/t't may concern: Be it known that I, Mormon KoHN, a citi- `zen of the United States, residing at- Chi` cago, county of Cook,` State` of Illinois, have invented a certain newand useful Improvement in Display Apparatus, and declare the `following to be a full,elear, and exact:` descript-ion of the same, such aswll` enable to make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification." l l 4 My invention has fo-rits object to produce a simple and novel apparatus in which a series of trays may be disposed in step-like formation` within a suitable case, be easily and quickly removed and replaced, and be capable ofbeing handled as a single iiat tray when removed `from theicase.

The various features of novelty `whereby my invention is characterized willhereinafter be pointed out with particularity `in the claims; but, fora fullunderstanding of my invention and of its object `and advantages, `reference maybe had to the following detailed description takenin connection with the accompanying drawings, wherein:

Figure l is aperspectlve view of an as-` sembled apparatus arranged in accordance with a preferred form of my invention; Fig. 2 is an end view of the apparatus, showing in dotted lines thedoor of the casing opened and the trays :in position to be removed; and Fig. 8 is an end view of the trays, showing the manner them when removed from the case. l

Referring to the drawings, 1 represents a suitably constructed casepreferably of glass for the purpose of exposing to view objects positioned within the case.` One side of the case, preferably the back, is made in the form of a door 2 which is hinged at its lower edge as indicated at 3. 4, 5 and 6 represent a series of `individual trays approximatelyas long as the mately equal to the depth or width of the case. The trays are connected together in any suitable manner so as to permit them to` be moved relatively toeach other, making 1 it possibleto bring them either into a step formation or into a formation wherein the several trays lie in substantially the same plane. In the arrangement shown, corresponding ends ofi the trays are connected specification of Letters Patent. Application inea July 5,1911.

together by two parallel bars, there being` j j the trays ,i j `as indicated at 7 and 8 `Eachof the bars is,

two of these bars at each end of pivotally connected or journaled to eachllof the trays, the pivotsforjournals beingindicated at9. The pivotal connections of the ratentedoct. e, `1914;

lbars are so arranged that any four ofthem at either end of two adjacent traysform they corners of `a parallelogram. The` parts are i so arranged that: the trays will lit nicely into the case when the rear tray is lifted lso as to bring it near the top of the case.` When not otherwise supported the trays tend to drop into a single plane so as to `permit all `of :them to rest upon a fiat surface. t The trays are held in their step-like formation by means of a door which, whenclosed, bears against the backofthe uppermost tray and prevents it from swinging out, the lower` most tray` bearing against the front wall of the case.v Consequently, when the door is opened, there is nothing to support the trays in their step-like formation and theupper nes descend with the door until they lie at. i i

It is often desirable to remove the `trays so as to permit a closer inspection to be made of their contents than can be had while the trays are in the case.` I therefore provide means `for facilitating the removal andthe handlingof the trays, and for preventing` the trays from being placed in the case in such a way that they are aptto become jammed when the door is closed. For the purpose of attaining someof these ends of my invention I i provide the rearmost tray, 6, with pins l0 projecting from the ends there-` of, andon the door I provide stopmembers i i l1 which are adapted to lie below the pins P when the trays are assembled in the case and the door `is closed, and to engage with the pins asthe door is `opened and partially withdrawthe trays from the case.` When `the trays are again inserted `into the case,

after having been removed therefrom, they are set uponthe `door with the pins l() just; outside of the stops 1l as indicated in dotted lines in Fig. 2; the stopsthus limiting the entrance of the trays into the casingjbefore the door is closed.: ,Then, when the door is raised for the purpose oficloslng the same,

the innermost tray slides along the bottom of the lease or across suitable rails 12 secured to the bottom while the `outermosttray rises with the door and is retardedl in its inward movements bythe stops which engage with the pins 10. In the preferred arrangement the stops are in the form of hooks Which have their open sides directed toward the upper edge of the door.

For the purpose ofpermitting the several trays to be handled in the samek Way as it gaged by hand grasping the tray 6 so as lto be held against the underside of that tray.

Thisv of course locks the trays 5 and 6 together and also holds the tray 4 and such other trays as there may be in the seriesv aga-inst movement. y

vshown the member 13 is in the form of a In the arrangement shelf at the center of the trays lout, as heretofore. stated, Vit may take other forms than this..

While I have illustrated and describedr only a single preferred form of my invention,'I do not desire to be limited to the particular structural details thus illustratedand described; but'intend to vcover all forms and arrangements which fall Within the terms employed in the definitions of my invention constituting the appended claims.

I claim:

1. In a display apparatus, a show case, a doorhinged at the bottom on one side of the case,l a plurality of trays movably connected together vand forming a series of steps extending downwardly from the'side having the door to the opposite side, pins projecting from the ends of the'uppermest tray, and hooks carried by the door in positions to engage with said pins when the door is opened, the open sides of the hooks `vbeing directed toward the door. f

2. In combination,` a' seriesoi1 trays, connecting meansfor the trays arranged to permit them to be adjusted from a step forma*- tion to a formation in which the trays lie `in 2 a. single plane7 and a number secured tothe underside of one of the intermediate trays and projecting under oneof the outer trays in a position to be grasped by a hand holding the latter trayy When the trays are in the plane formation.r u

In testimony Whereo, I sign this specification in thepresencev of tivo Witnesses.
